Application filed December 29, 1924. Serial- No. 758,764.

present invention is designed primarily forusein poultry cars, it'islikewise of such construction as to be useful to campers andtourists,and, in fact, is practically univer- F sally useful.

Oneof the objects of the present invention I is to provide a stove ofthe class mentioned which will be simple and durable in construction andcheap to manufacture, and

which may be conveniently carried about from place to place and readilyset up for use wherever required."

, Another object of the invention is to provide'a stove soconstructed'that the space beneath the bottomof the-ash pit will bethoroughly ventilated so that when the stove is employed in a poultrycar, there'will be no likelihood of overheating of the floor of the carat the point where the stove is located. 7 I

Another object of the invention is to provide, in a'stove of the typereferred to, a novel construction of grate which may be produced at anextremely low cost and which may be readily removed if occasion shouldrequire.

Another object of the invention is to .provide a novel construction oftop or lid in a stove ofthis type to adapt it for supporting cookingutensils without likelihood of the utensils slipping from the lid.

Another object of the invention is to provide a stove which may bereadily and conveniently anchored to the floor of a poultry car andsecurely held against accidental overturning.

In the accompanying drawings:

Figure 1 is a perspective view of the stove embodying the invention.

Figure 2 is a vertical front to rear sectional view therethrough, on theline 2,2 of Figure 1, looking in the direction indicated by'the arrows.I

Figure 3 is a horizontal sectional view taken substantially on the line3-3 of Figsition to close I the door opening ure 2, looking inthedirection indicated by the arrows.

The stove embodying the lIlVBlltiOll comprisesa hollow cylindrical bodyor orum indicated by the numeral 1 and formed of sheet metal, the drumbeing designed to rest at the lower edge of its wall, upon the surfaceupon which the stove is disposed for use,

and the body being closed a suitable distance above its lower edge by anupwardly bulged sheet metal bottom indicated by the numeral 2 andprovided with a circumscribing flange Sriveted or otherwise secured asat a, to the wall of the body'l. As the bottom 2 is spaced above thelower end of the drum and consequently above the surface upon which thedrum is disposed, an air space 5 is provided beneath the bottom 2 andthe wall of the drum isformed with a number of openings 6 below the saidbottom. 2 to provide for free circulation of air within this stove isdisposed. The bottom2 constitutes the bottomof the ash pit of the stoveand, in order that ashes may be readily removed from the ash pit, a dooropening 7 is formed in the wall of the drum 1 and the portions of thewall at the opposite sides of the opening are bent outwardly against theouter space and thereby prevent the overheating ofthe floor or othersurface upon which the side ofthe wall and thence backupon themselves toprovide vertical guides 8 in which are slidably received the verticaledge portions of a sheet metal door 9 adapted to be slid vertically intoand out of poor to partly close the same in order to provide forregulation of draft, the lower side of theopening being substantially atthe level of the bottom 2. In order that the door may be convenientlyadjusted, its upper edge portionis turned outwardly to its area, and thesaid plate is of a diameter to fit within the drum 1 and be supportedabove the bottom 2 and in a plane above the upper side of the ash dooropening 7.

Inorder to support the plate, a'plurality of rods 13 of small diameter,preferably three in number,are secured at their ends through the wall ofthe drum and each rod extends diametrically of the interior of the drum.Preferably, each rod 13 is formed at one end with a head 1st and at itsother end is threaded and provided with a nut 15, the rods being, inthis manner, held against longitudinal displacement and, at the sametime, being capable of being readily removed in the event it becomesnecessary to replace any of the rods. One of the rods 13 is led on astraight line diametrically across the interior of the drum While theother rods are suitably deflected, as at 16, in a downward direction, topermit of their intersection below the first mentioned rod. However,this does not impair the usefulness of the rods or their efficiency assup porting means, for the periphery of the grate plate 11 is supportedupon the end portions of the rods near the points where they projectthrough the wall of the drunr By bulging the grate plate, it isunneccssary to employ a cast grate inasmuch as the plate, due to itsform, will be capable of sustaining a considerable weight'andconsequently fuel as heavy as coal may be burned in the stove, coal,wood, and charcoal constituting the fuels which will ordinarily be used.

The drum 1 is closed at its upper end by a fixed top section indicatedby thenumeral V lTand this section is of segmental form and is providedwith a downwardly projecting peripheral flange 18 which fits about theupper margin of the wall of the drum and is riveted or otherwisesecured'thereto. A stove pipe thimble 19 is secured in an opening in thefixed top section 17 for the connection of a stove pipe or flueindicated by the numeral 20. The numeral 21 indicates a movable topsection or lidwhich is of sheet metal and of segmental form, and thechordal edge of the section 21 is formed at intervals with pintle ears22 asis also the chordal edge of the fixed section 17,

and a pintle rod 23 is fitted through the ears and serves to hingedlyconnect the section 21 with the section 17. The section 21 is,therefore, adapted to be swung upwardly to permit of the introduction offuel into the firebox of the stove and, in its lowered posi tion, restsat its under side upon the upper edge of the wall of the drum 1. Thearcuate edgev of the section 21 is formed with an upstanding flange 24,and an arcuate strip 25 of metal, is disposed against the outer side ofthe flange and riveted or otherwise secured thereto as at 26. At thispoint it will be evident that the top of the store may support cookingutensils and that, due to the provision of the flange 24, which isreinforced by the strip 25, such utensils are prevented from slippingoff from the top section or lid 21.

In order that the stove may be anchored in place and prevented fromoyerturning, as for, example when employed in poultry cars, loops 27,made of suitable bent sheet metal strips, are riveted or otherwisesecured to the wall ofthe drum 1 near the top of the drum and atdiametrically opposite sides thereof, and wires 28 are connected attheir upper ends to the loops and are led downwardly and outwardlytherefrom and connected at their lower ends to nails or other fasteningelements 29 driven into or secured to the floor or other surface uponwhich the lower end of the drum 1 is disposed.

Having thus described the invention, what 1 claim is:

A. heating stove comprising a vertically disposed body, and a closurefor the upper end of said body, said'closure including a stationaryection and a movable section, the movable section being of greaterdimensions than the portion of the body to be closed thereby and havingits marginal portion projecting outwardly from the body and providedwith an upstanding flange constituting a guard flange to retain articlesupon the upper face of the movable section, and a reinforcing stripsecured against the outer face of said guard flange, the reinforcingstrip being of greater depth than said guard flange and projectingdowmvardly therefrom below the plane of the movable section intooverlapping relation to the walls of said body and providing a dependingtlangeadapt'ed to be engaged when the movable section is swung upwardlyto an open position.

In testimony whereof I a'tlix my signature.
